The time it will take for the car to skid for 150 feet is 8.23 seconds.

<h3>How to find the time the car will skid?</h3>

The function D(t) = 18t² − 130t gives the distance a car going a certain speed will skid in t seconds.

The time the it would take for the car to skid for 150 feet can be calculated as follows:

Therefore,

D(t) = 18t² - 130t

150 =  18t² - 130t

18t² - 130t - 150 = 0

divide by 3

9t² - 65t - 75 = 0

Hence,

t = 65 ± 5√277 / 18

t = 8.23425471586 or -1.01166666667

Hence,

t = 8.23 seconds.

Therefore, the time it will take for the car to skid for 150 feet is 8.23 seconds.

mixas84 [53]
This is a right triangle so the total angle is 90 degrees.
90 degrees - 20 degrees = 70 degrees, so 2x = 70
2x/2= 70/2

Using inductive reasoning, what are the next three numbers in the sequence 3, 6, 12, 24? 48, 96, 192 36, 48, 60 30, 48, 56 72, 1
Andrej [43]
For the sequence each term is obtained by multiplying the preceding term by 2.

3, 6, 12, 24, 48, 96, 192

Therefore, the next three terms are 48, 96 and 192.
